Caribbean reef squid communicate with each other by changing colors. They do this by controlling their color-changing cells called chromatophores. Each chromatophore contains a sac filled with pigment. When they expand their chromatophores, the color becomes brighter and when they contract these sacs, the color is dulled. These creatures have complex nervous systems that enable them to expand and contract these unique cells.
